Semaj Miller was gunned down the afternoon of July 29 near Main Street and East 87th Place. Police believe a gang member may have carried out the shooting. The suspect remains outstanding.
Hundreds of friends, family and community members appeared at a vigil for Semaj on Thursday, mourning the young man who was described as having a bright future.
Semaj started playing basketball at age 11. He started getting better and better - and kept growing and growing, reaching a height of 6 feet 6 inches by age 14.
He played ball for the Wildcats Youth Academy, which was established a few years ago to give young people a safe place to learn and have fun.
Academy founder Derrick Cooper says Semaj was a special kid with a good heart.
"We want justice," Cooper said. "We want answers. And we want accountability. This young man did not deserve to die that way. He was a phenom, a superstar basketball player. He was wanted all over the state."
"He is someone that had a promising future. To take that from him - unacceptable."
The motive for the shooting remains undetermined.
The Los Angeles Police Department asked anyone with information to call South Bureau Homicide at (323)786-5100.
